Volleyball hitting training device

ABSTRACT

A volleyball training apparatus has a laterally extending arm supported on a riser. A resilient member such as a spring is operably connected within the arm. The resilient member is connected to a flexible connector, such as a cable, that is connected to a volleyball. A series of spacers retains the volleyball away from the rigid arm. The height of the arm may be adjustable to locate the volleyball at a desired height. After a user strikes the volleyball, the volleyball is displaced from its original static position, but quickly is snapped back into the static position by the resilient member pulling the volleyball toward the arm against the spacers.

No. 17/248,697, filed Feb. 3, 2021, which is a nonprovisional claiming priority pursuant to 35 USC § 119(e)(1) to U.S. Provisional Patent Application No. 62/969,442, filed Feb. 3, 2020.

FIELD OF THE INVENTION

The present invention relates generally to athletic training equipment and more specifically to a device to aid in training players to hit or spike a volleyball.

BACKGROUND OF THE INVENTION

There are a few classes of common commercially available volleyball spike trainers. The first group holds the volleyball stationary with friction, and then releases it when hit; which requires chasing down the loose ball and re-loading the device. Another class tethers a ball with a loose cord attached to either a support, a ceiling, or to the user. These devices eliminate the need to chase down loose balls but suffer from the disadvantage of either not holding the ball in a consistent location, or not damping the movement quickly. A third class attaches the ball between two bungy cords or elastic bands. This arrangement does overcome the need to chase the ball, and depending on the stiffness of the elastic cord, may rather quickly damp the motion to return the ball to a stationary position. However, it is disadvantageous to use two elastic elements instead of one because the ball reacts differently when struck and because of the inefficiency of using (and supporting) two elastic elements instead of one. These two elastic element devices also run the risk of tangling with a user's arm or wrist which can be uncomfortable at best and risks injury at worst.

It is also known to attach a volleyball to a single elevated arm with a spring. However, these suffer from the disadvantage of the ball not quickly returning to its starting position after being struck such that it can be quickly reused, especially in a line drill.

Portable training devices that include frame and a ball that is struck by a user can be susceptible to moving by “wandering” as repeated lateral force is applied to the frame. The wandering can result in the apparatus moving to an unwanted location during use.

Volleyball players benefit from striking a ball as high above the as possible. Receiving feedback on how high they are hitting the ball can be a valuable tool for improving hitting and jumping height. Accordingly, there is a need for a training device that provides feedback to a user about how high they are striking the ball.

Accordingly, there is a need for an improved volleyball training apparatus that overcomes or diminishes the disadvantages of the prior art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

FIG. 1 shows a volleyball training apparatus 10 according to one embodiment of the present invention. The apparatus 10 includes an adjustable riser structure 12. The riser structure may include a vertical upright riser 14 and a base 16. The base 16 may include wheels or rollers 18 at a first end to make it easier to move the apparatus 10 to a desired location. A second end of the base opposite from the rollers 18 may include pads or friction material (not shown) to prevent scuffing of the floor and to resist sliding of the apparatus during use. The riser structure 12 preferably includes an adjustment mechanism 20 to facilitate the raising and lowering of the vertical riser 14. A lateral arm 22 extends generally horizontally from the vertical riser 14. The lateral arm 22 may be formed integrally with vertical riser 14, or may be a separate piece that mounts on to the vertical riser 14. At the distal end of the lateral arm 22 is an end cap 24, spacers 26 a, 26 b, and 26 c, a padded collar 28, and volleyball 30. A chain 32 is used as a tension adjustment mechanism in a manner that is described below.

Use of the training apparatus 10 is illustrated in FIGS. 2A, 2B, and 2C. The vertical riser 14 is adjusted to position the volleyball 30 to a desired height. A user (volleyball player) approaches the volleyball 30, leaps into the air, and strikes the volleyball 30 with his or her hand 34 as shown in FIG. 2A. Providing a consistent location of the volleyball 30 helps a user 34 focus on technique and provides feedback to the user and the user's coach about how changes in technique affect the height of the user's jump and quality of contact with the volleyball 30. The apparatus 10 may be located near a net (not shown) to simulate game conditions and to provide additional feedback and training related to positions for the user's run-up, jump and landing. Ideally the user should be able to raise the volleyball 30 to higher heights as the user's technique improves through use of the apparatus 10.

As seen in FIG. 2B, after the volleyball 30 is struck by the user 34, the volleyball 30 is displaced from the static position of FIG. 2A. The provides feedback to the user 34, permits a realistic simulation of the feel of hitting a volleyball 30 during play, and allows enough give to avoid uncomfortable or even potentially injurious contact that might occur if the volleyball 30 was rigidly mounted. As seen in FIG. 2C, the volleyball 30 rather quickly snaps back into place in the static position so that it is ready to be struck again, either by the same user or another user—for example in a line drill.

FIG. 3 shows a training apparatus 36 that is adapted to be added to an existing riser structure. For example, the apparatus 36 could be used with an existing riser with square tubes, such as commonly used to support basketball backboards in portable or driveway installations. The apparatus 36 includes a vertical stub 38 extending below the proximal end of the lateral arm 22 that is adapted to mate with an existing riser. Otherwise, the structure is essentially the same as shown FIGS. 1 and 2 and in fact could be used with the riser structure 12 of FIGS. 1 and 2 , except that the riser of FIG. 2 uses circular rather than square tubes. It is contemplated that the lateral arm 22 and especially the vertical stub 38 could be shaped as needed to cooperate with any common riser structure. Also more readily seen in FIG. 4 end cup 40 is covered by a padded collar 28. As seen in FIG. 4 , the end cup 40 has an open end facing the volleyball 30 to allow the volleyball 30 to seat securely against the walls of the end cup 40.

FIG. 5 shows the internal components of apparatus 36 in an exploded configuration for better understanding. A cap 24 abuts and covers an open end 46 of the lateral arm 22. The cap 24, spacers 26 a, b, and c and end cup 40 all include central openings to receive a flexible connector 48 that passes through each of the cap 24, spacers 26 a, b, and c and cup 40 and connects the volleyball holding straps 50 to a resilient member 52. The volleyball holding straps 50 may be two nylon straps provided with metal rings or eyelets (not shown) to provide a connection location for the flexible connector 48. Other known mechanisms for attaching a volleyball to a flexible cord may be used. In the embodiment shown, the flexible connector 48 is made from ⅛-inch braided wire. Other materials and structures may be used as the flexible connector 48. A helical tension spring serves as the resilient member 52 in the shown embodiment. Other resilient devices, such as elastic cords or other types of springs may serve as the resilient member 52.

FIG. 4 is a cross-section view of a training apparatus 36 of FIG. 3 . A generally hollow lateral arm 22 is attached to a vertical stub 38 that mates with an existing riser structure. Alternatively, the lateral arm 22 and vertical stub 38 may be formed from a single hollow tube bent to the desired shape. The vertical stub 38 may include a passage to permit a pin or other retaining member (not shown), to secure the apparatus 36 to the riser. At a proximal end of the lateral arm 22 a spring adjustment mechanism is provided. In the embodiment shown, the spring adjustment mechanism comprises a chain 32 attaches to the resilient member 52 and can be pulled through an opening 39 in the vertical stub 38 to adjust the tension in the resilient member 52. A hook or other protrusion (not shown) may be provided on the exterior of the vertical stub 38 to capture a link in the chain 32 and retain the chain 32 in place. Alternatively, as shown, the opening 39 in the vertical stub 38 may be a slot that only permits passage of the links when oriented in first direction, and the chain 32 may be held in place by twisting the chain 32 to the opposite orientation outside the slot 39. In any event, the chain 32 or other spring adjustment mechanism should be pulled tight to pull the volleyball 30 via the cable 48 and the spring 52 tightly against the cylinder 44, which in turn presses against end cup 40 and the spacers 26 a-c, which are pressed against the end cap 24. FIG. 7 shows the apparatus 36 of FIG. 6 with the spring adjustment mechanism 58 pulled tight such that the volleyball 30 is in position for use.

Returning to FIGS. 2A-C, with the structure illustrated in FIGS. 3-5 in mind, it can be seen that once the volleyball 30 is struck by the user 34, the volleyball 30 through its retraining straps 50 pulls against the flexible cable 52 and thereby stretches the resilient spring 52. This permits the volleyball to be temporarily dislodged from the static position of FIG. 2A as shown in FIG. 2B. However, as shown in FIG. 2C, the spring 52 pulling against the cable 48 quickly returns the volleyball 30 to the static position with the spacers 40, 26 a-c, and 24 in contact with each other and the movement of the volleyball 30 quickly arrested. The use of multiple spacers 26 a-c instead of a single spacer is preferred because it permits greater flexibility in system and creates less stress as compared to a single larger spacer.

FIGS. 6 and 7 illustrate a preferred weighting system that can be used to retard unwanted movement or wandering of the device 10 that can result from repeated striking of the volleyball 30. In particular, weights 60 may be placed on the base 16 to increase the friction and inertia that impede sliding of the device 10 on the floor. Angle irons 62 provided on the base 16 of the riser structure 12 serve as support structures for supporting the weights 60. In a preferred embodiment the weights may be hollow containers that can be filled with a weighty substance. The hollow containers help reduce shipping weight. For example, the weights may be water jugs 60 that are shipped empty and then filled with water at the use site. Alternatively, the hollow containers 60 may be filled with sand or similar sold flowable material. The weights 60 may be slid on the angle irons 62 or other support structure between the position of FIG. 6 where the weight 60 is located a distance away from the wheels 18 to produce maximum friction with the floor and the position of FIG. 7 , where the weight is near the wheels to make it easier to tilt the riser structure 12 for rolling movement of the device 10.

FIG. 8 shows a training device 101 according to another embodiment of the present disclosure. The training device 101 is similar to device 10 except as specifically noted. The base 16 of training device 101 includes a pair of side member 16 a, a first end member 16 b and a second end member 16 c. Each of the members 16 a,b,c of the frame may be angle irons welded together to form a generally rectangular frame. Other materials and formations may be used to form the base 16 that acts as a support for rest of the training device 101.

The training device 101 includes handles 109 that are mounted to and extend from the riser 12. The handles include a grip portion and a shaft portion. The shaft portions are attached to and extend from the riser 12. The grip portions are adapted to be grasped by a user to manipulate and move the training device 101 on the rollers 18 that are connected to the base 16 at the second end of the base 16. The shafts of the handles 105 may be used to support weights 103 when the device 101 is not in use or when it is being moved.

Shock absorbing feet 109 are mounted to the first end member 16 b. The shock absorbing feet 109 may include a resilient member 111 such as a coil spring and an end cap 113 adapted to engage the floor. The weights 103 may be moved to provide additional pressure on the feet 109 when the training apparatus is in use. Spindles 107 may be provided on the first end member 16 b in order to secure the weights 103 directly, or nearly directly, above the feet 109 in order to increase the friction between the end caps 113 of the feet 109 and the floor.

Details of the shock absorbing feet 109 and how they mount to the base 16 can be seen in FIG. 9 . Mounting hardware 110 may be mounted to the lower side of angle iron 16 b. The mounting hardware 110 secures the resilient member 111 to the base 16. An end cap 113 is attached to the lower end of the resilient member 111, for example by a friction fit. The end cap 113 is preferably a relatively high friction material in order to have a good grip with floor. Also, the end cap 113 is preferably a non-marking material that will not leave marks of mar a floor. Spindles 107 may be provided above or nearly above the feet 109. The spindles 107 may be bolts or bolt like structures that provide a location to place weights 103. The weights 103 when in position on the spindles provide extra downward pressure on the shock absorbing feet 109 to increase the friction force between the feet 109 and the floor. The resilience of the resilient member permits some movement of the training device 101 relative to the end caps 113 without the end caps 113 sliding or hopping on the floor thereby retarding wandering that would otherwise occur because of the repeated transverse forces applied when the volleyball 30 is struck by a user.

The training device 101 also includes a gauge 115 that can be used to indicate to a user how the volleyball 30 is above the floor. The height of the lateral arm 22 relative to the riser 12 may adjusted using an adjustment mechanism 20. Those of ordinary skill in the art will be aware of several mechanisms for adjusting the height of the lateral arm 22 relative to the riser 12. In the embodiment of FIG. 8 , the adjustment mechanism 20 includes a crank 117 that can wind up and let out a belt 119 to raise and lower the lateral arm 22. The gauge 115 may include uniformly spaced markings and labels similar to a tape measure or ruler. In a preferred embodiment, as shown in FIGS. 10A and 10B the gauge 115 is positioned and labelled such that the height of the volleyball 30 when it is in the static hitting position is displayed at the junction between the lower portion of the riser and the upper portion of the rise. For example, in FIG. 10A the volleyball is about ninety-nine (99) inches above the floor. In FIG. 10B the lateral arm 22 has been raised two inches, such that the volleyball is now about one hundred one (101) inches above the floor. This information can be very valuable to a user. It provides feedback about what techniques work for increasing the user's strike height and can be used to track progress and improvement as well as set aspirational goals.

Thus, various configurations of a volleyball training device have been shown and described. It should be appreciated that the embodiments shown and described are for exemplary purposes, and the invention of a volleyball training device has thus been provided.
